Is it possible to change the gravity of a single Rigid Body in the scene?
This is related to How can I make scene with multiple gravities going in opposite directions without using a force field?
It used to be that you could move rigid bodies into different layers and they would only be affected by the forces within that layer. This would allow you to create a force (such as Drag) which would only affect some of the objects. However, at later versions of Blender, that functionality is broken - see https://developer.blender.org/T87458.
Once that bug has been addressed it should be possible to have forces affect only certain objects by putting the objects in different Collections.
